The coordinate-axes displayed using the "Axes" module cannot be scaled easily. Using this Xtra, you can easily change the lengths of the axes and the location of the displayed origin.
Invoke the "Scale Axes" module (located in "Xtra>Annotations") at an existing "Axes" module.
You can change the length of each displayed axis separately using the sliders in the module's properties. It is also possible to move the origin of the displayed axes. If the allowed value-range is not enough, you can adjust it after pressing the "..." buttons.
Note: The "Axes" module automatically changes the thickness of the displayed axes at certain length values. You can change that behavior by adjusting the "Axes" module's "Thickness" property.
